Doesn-LEAF BINDER.

vApplication, mea,- Mareh 15, 192.6. serial No. 94,71?.

such sheets are being collected, that they,

4may be'temporarily bound until the assembly for a volume is completed.It is a primary object and purposeof the present in# vention to providea binder for record sheets and the like which may be used tobind thesame temporarily in order thatl other sheets may be added until thedesired number a volume is attained, whereupon covers may be added to'the temporary binder Vand Vsealed in place in such a manner that thevcovers cannot be removed nor thepart-s of the temporary binder reached,so that .by the addition of such covers and theirper` manent connectiona permanent binding of the sheets in a volume is secured.

A' further object of the invention is to provide a binder of the-classdescribed which is very simple in construction, economical tomanufacture and durable and efficient in its operation. The meanswhereby these 'ends are attainedas well as many others not at this timeVspecifically stated, is lfully dis:- closed in the followingdescription taken in connection with the accompanying drawings, `inwhich Fig. l is a perspective view illustrating a number of sheets, themethod Vused for temporarily binding the same andthe parts which go tomake up said binder, the same being shown in -separated condition.

Fig'. 2 is a similar view showingrthe parts together and in positiontofeffect a temporary bindingofthesheets. Fig. 3 is a fragmentarysection illustrating slightly different form of ybinding means.

fFig'. 4 is a fragmentary perspective 'view showing the cover used andapplied to the temporary binder to make Athe same permanent.

5 is a fragmentaryenlarged trans- 2'verse section through the backportion of a volume permanently bound together, the

1n hinges.

Fig. 6 is a lperspective view of one of the leaf holding members used,and

Fig. 7- is arear elevationl ofA a. volume permanently bound, theconnecting back between the two covers being shown in section' Y Aso asto disclose the rear end ofthe volume which is ordinarily covered bysaidback.

VLike referencev characters refer to like parts in the d ifl"erent,igures in the drawlngs. f The sheets which are to be bound together areindicated at l and at theirback edges are provided with apluralityY ofapertures or notches'2 `of the. form shown, the same being4 adapted to.have the leaf holding members pass therethrough.'k Thev leaves may beplaced, `one over the other, thebottom'leaf, atvits back edge, lyingagainst the lower binding bar-which is of angle' forni having a bottomflange?)- and a back vertical flange 4. The bottom fiang'e' at vits forv` ward edge is formed with `a lplurality of spaced apart rolls 5, thesame, as are used Said Vvbottom flange' 3 also, at 'spaced apartpointsin its length,v has slotsl 6 cut therethrough for the passage yoflower leaf holding membersA 7 upwardly through saidopenings. The members7 vrare' of flat f stock narrowed at their upperportionsv to make thetongues andat their lower ends being turned at right angles making theflanges 9 which bear against thelower sides of the lower flange 3 -ofthebottom binding `bar. YThe leaves, when passed over the Aleaf holdingmember 7 are held by said v'members as they tures 2, asis obvious.

hinge Vrolls 51. 'Also the vupper flange 3l i has Aa `number ofspaced-.apart slots vGlfcut pass through the notchesorfaper- When a number'of the leaves havebeen f i put 'together' to form the ,leaf bodyan upper binder bar is Aapplied to. the leaves.'

therethrough, one for each ofthe leaf mem'-v bers, tongues 8 extendingupwardly through saidrslots G1.- Companion leafmembers 1 0 of flat formareVv4` inserted downwardly through the/slots 6l, each of said members1@ at its upper end being wth'a flange 11 having a slot 12 thereinthrough v`which the vtongue y8I of the' lower associated leaf member 7may pass. As thusapplied to the leaf body the tongues 8 may be bentbackvvardly, as shown in Fig.v2, to effectv the securing ofthe leaves orsheetsjtogether,

it being evident that Whenever desired the tongues maybe bent back tovertical position :so rthat the upper clamping bar niayV be removed forthe additionvof other sheets or leaves. V' i Inl Fig. 3 a modified formof structure forefi'ecting the temporarily binding of sheetsor Aleavessshovvn, the leaf members 71and`10 being supplanted by a U-shaped `Wirehaving a bottom portion 13 and vertical spaced apart legs 14'Whichmay'pass through suitable openings in the lianges 3 and 31 of the lowerand upper binding bars.

lThe projecting upper ends of the legs l14 are bent inwardlytoward eachother, as indicated at 15,'and into slots cut intoflange 31 of the upperbinding bar. In all.cases, irrespective of how the actual leaf vengagingmembers are made, the horizontal {ianges 3' and'l of thejtWo bindingbars are prol videdv at theirforwar'd edges, vin front of Where the leafholding members pass through said flanges, With the' hinge rolls 5 vand51', Vthe purpose vof which will later ner that they are permanentlybound `and no'further addition to or removal from the volume can `takeplace. K

The cover consists of tivo leaves 16 con? nectedA at their rear edges bythe usual back To each `of the covers 16`on their inner sides and near:their back portionsfhinge plates 18 are permanently secured by rivets orotherwise,r the same, at their rear' edges being' formed with spacedyapart hinge rolls 19 which are so' located with reference to eachrotherfthat the hinge rolls and 5l on the flanges'fand 81 of the'bindingbarsma'y'be Vreceived in the'spaces between said hinge rolls 1,9 andhinge rods, shown at 21, pass through the alined openings made bytherolls 5l and Y 19`and 5'1 and`19. One oftheiparts 5 and 51 atv oneend, of the binding bars", is equipped Witha short headed pin 2O whichis driven intoz the end of the rolls 5' and 51 so ras `to be permanentlysecured.V AIn fact,r to

make the connection permanent and one which cannot be disturbed it isour practice to solder' such headed pins 20 in place. These pins 20 arebest shown in Fig. 7. The

.tance from theoutcr ends of the outermost rolls v5 Amd 51 le n`f i1`ig,a'spa'ceV shoivnat 22 in Figi.` This makes the rods 211naccessibleso'fthat the same cannot be removed and, in practice, We flatten, upsetor enlarge the ends of the rods 21 thereby making theml fit l tightlyi`into the rolls so vthat When driven fully into place the Asame are veryscct'ire'ly' held by friction at the enlarged end against anypossibility. offdlongitudinal movement.'k y' f Y i It Will be noted thatby sition of the hinges the yupperv rearwardly bent 'ends' of thetongues 8 are inaccessible so that the temporary binder which is madebefore the covers arer applied, becomes a permanent binder' WithV the'application of thecovers in" the'manner outlined;v The onlyway that theupper ends of'the tongues 8 Vor., if the modification shown in Fig. disuse`d,'the upper ends 15 of the legs 14, can

be raised,y is by destruction ofthe back 17 i Awhich, of course,involves destruction of Vthe binding of the book..y The' construction'Shown' and described is especially adapted reason of the pfoforkhandling public records required in perj.v

marient bindings whichVH cannot be bound loosely, subject as they mightbev to removal under such circumstances.V At the same time the actualbinder' which is used ico in the finished book serves, AWithout change,

the purpose of a temporary binder during the' time that the volume" isbeing made up. y .The construction outlined has beenfound very practicaland eihcient. Many variay vtions in minor detail ofk construction'may beresorted to Without departing from the invention which is defi-ned inthe appended claims and We consider ourselves-entitled to all forms ofstructure which come Within the scope of said claims.
